using LED Indicator globes with Bellagio Computer

Am on my third set of Indicator globes (in only 8000 Km). Thinking of trying aftermarket automotive LED replacement globes, cheaper than the Guzzi replacement,, 20,000 hours running time, vibration resistant.

Bellagio has a gnome in the trip computer whos job is to alert me of blown globes. Does anyone know if this will still work with LED's? Resistance of the new assembly is likely to be much higher than a 10 watt globe. How clever is the gnome?
 
Dunno about your gnone, but it's intrigued me for years about substituting LEDs for incandescent lamps.

What I would be tempted to try is a resistor in parallel with the LED-resistor series combination to try and maintain a similar load to what was originally present. With simple make or break contacts like the oil pressure switch it probably isn't necessary, but something like the fuel level light, I would anticipate it vital. This approach would be for the older arrangements, not a modern bike like the Bellagio complete with Gnome.

Alternatively, why don't you consider inserting a low value (but reasonable wattage) resistor in series with your indicator bulbs, enough to reduce the voltage by around 10%. You shouldn't notice much difference in brightness, but the life span should be increased several fold.

Just a thought.
 
I don't know about the wiring on a Bellagio but my supplier of electrical bits for old Brit bikes told me you have to use a different type of flasher unit with LED indicators. I guess he must know his stuff as he sells loads of LEDs to people fed up with those good old British vibes killing bulbs (that's if the whole indicator hasn't shaken itself free already & isn't lying in the gutter somewhere back up the road!)
 
Have a look here.

It is likely that your gnome will see the LED indicators as open circuit, so you will either have to find indicators with ballast resistors built in, or add ballast resistors in parallel with each indicator, just to fool the gnome.
The indicators are controlled by the dashboard computer, so no alternative flasher contol is possible.
 
I'd guess drop-in replacements that are "seen" as old-style bulbs should be available by now??
 
Yes, not sure if they turn signal bulbs are available as (proper) resistor types... but the conventional stop-light bulbs have been for almost a decade. If someone finds something that works, plug-in and go, please post it here.
 
Well the guy on Wildguzzi said.
Found them on Ebay, cost was $65 including shipping. Spent about 30 minutes installing them. Connect right to the stock turn signal connectors. According to the package the same set will also work on all models of the Breva, both front and rear. I think they look pretty cool myself.
So I would guess that either they have a ballast resistor built in or the gnome accepts them as not being open circuit.
Either way, they should work for the Bellagio.
 
Hmmm, now if only we knew where on eBay these thingies can be had ... and if they exist with the additional brake light function!
 
I've thought about adding one to mine, but it seems a real hassle to take the box off afterwards ... and I only put it on when I really need it...
 
Purchased a couple of the LED array globes from my local Dick Smith store (an Ausie electronics parts chain for those eleswhere), 19 Yellow LED's arranged on a bayonet housing and intended as a substitute for automotive incandescents globes. Thought I'd try the pair on one side to see if the gnome noticed. After fitting the first to the rear, found I had to swap the wires in the indicator assembly to get it to work, after that, all seems fine, the gnome hasn't noticed the swap and light output is excellent...for the rear!! The array is larger than the original globe and gives a nice intense yellow light but not as broad a beam as the original incandescent. For the front indicators, I'd like to be visible from any angle, the LED beam is just too narrow unfortunatly. From the rear, viewing should be from behind only so not as much a problem.

Noticed also that even with the ignition switch off, there is sufficient residual current to get the centre LED to glow (noticibly in the dark, almost inperceptable in light). My guess is that this is the gnome at work, moniitoring the globe status even when I'm asleep. Leakage would not be more than 1 mA, don't think it will have any ill effect on battery.

So: now have LEDS at the rear, globes at the front, two spare globes in my kit and gnome is happy!
 
Are their warnings on the Bellagio? On the Norge, those will continue to work even with the ignition off, and I guess that might mean there's some rest current or leakage even when they're not used.
 
I think the Bellagio has the same computer as the Norge, has a little red triangle that flashes menacingly at intruders in the night, like a firefly bravely trying to imitate a real anti theft device!

The little orange glow from just the centre LED in the array is ctually quite practical, means I won't stumble into the back of the machine when drunk!

I'm guessing the LED replacement globe has a bleed resistor built in or it wouldn't work with most auto flasher cans. Will know for sure after a days riding tomorrow.
